This is a Hacker News discussion thread about a Daily Neuron article on aphantasia (inability to visualize). The source text is predominantly user comments rather than the original article itself—the article link is mentioned but its content isn't provided. What we have instead is a long conversation where people describe their personal experiences: some report having aphantasia yet still dreaming visually; others discuss lucid dreaming attempts; several mention spatial reasoning abilities despite lacking visual imagery; a few describe experiences on psychedelics or meditation. There's also debate about whether the whole phenomenon is real or semantic confusion about what "imagination" means. The actionable takeaway: if you're researching aphantasia, this thread documents consistent self-reports that visual dreams can occur independently of waking visualization ability, and that spatial cognition and other sensory imagination (music, touch) vary separately from visual imagery. But the original article's specific claims, evidence, or novel findings remain absent—you'd need to read Daily Neuron directly to know what's actually "rewriting the science."
